■Note for the entry function
● Even when the electronic key is within the effective range (detection
areas), the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle,
near the ground, or in a high place when the doors are locked or
unlocked.
• The electronic key is on the instrument panel or floor, in the glove box, or in the auxiliary box of the instrument panel.
● As long as the electronic key is within the effective range, the doors may
be locked or unlocked by anyone. However, only the doors detecting the
electronic key can be used to unlock the vehicle.
● The doors may lock or unlock if the electronic key is within the effective
range and a large amount of water splashes on the door handle, such as
in the rain or in a car wash. The doors will automatically be locked after
approximately 60 seconds if a door is not opened and closed.
● If the wireless remote control is used to lock the doors when the elec-
tronic key is near the vehicle, there is a possibility that the door may not
be unlocked by the entry function. (Use the wireless remote control to
unlock the doors.)
■ Notes for locking the doors
● Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
● When the lock operation is performed using the lock sensor, recognition
signals will be shown up to two consecutive times. After this, no recogni-
tion signals will be given.
● If the door handle becomes wet while the electronic key is within the
effective range, the door may lock and unlock repeatedly. Place the key
in a position 6 ft. (2 m) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
● If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a buzzer will sound outside the vehicle. To turn off the
alarm, lock all the doors.

●
The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again, or
use the lock sensor on the lower part of the door handle.
● Fingernails may scrape against the door during operation of the door
handle. Be careful not to injure fingernails or damage the surface of the
door.
■ Notes for the unlocking function
● Gripping the door handle when wearing a glove may not unlock the door.
● A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the
original position and check that the doors unlock before pulling the door
handle again.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.
■ When the vehicle is not dr iven for extended periods
To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2
m) of the vehicle.
■ To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from
the outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention function may
not operate.)
■ If the smart key system does not operate properly
● Locking and unlocking the doors: Use the mechanical key. ( P. 597)
● Starting the engine: P. 598

CAUTION
■Wearing a seat belt
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.
Failure to do so may cause death or serious injury.
● Ensure that all passengers wear a seat belt.
● Always wear a seat belt properly.
● Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
● Toyota recommends that children be seated in the rear seat and always
use a seat belt and/or an appropriate child restraint system.
● To achieve a proper seating position, do not recline the seat more than
necessary. The seat belt is most effective when the occupants are sitting
up straight and well back in the seats.
● Do not wear the shoulder belt under your arm.
● Always wear your seat belt low and snug across your hips.
■ Seat belt pretensioners
● Do not place anything, such as a cushion, on the front passenger's seat.
Doing so will disperse the passenger's weight, which prevents the sensor
from detecting the passenger's weight properly. As a result, the seat belt
pretensioner for the front passenger's seat may not activate in the event of
a collision.
● If the pretensioner has activated, the SRS warning light will come on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
■ Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your
shoulder. The belt should be kept away from your neck, but not falling off
your shoulder. Failure to do so could reduce the amount of protection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or accident. ( P. 80)

erly, do not touch or cover them.
